back to basics

Frustrated at the inability of Google to provide a simple sync process that works for disparate versions of Chrome and Chromium browsers, I decided to adopt a pragmatic approach, return to Victorian values and go back to using a Web based bookmarks service.

Way back, in 2005, I evaluated three different bookmarking services and dismissed Delicious, mainly on the grounds of the user interface design of the home page which, according to me, 'looks like an undergraduate knocked it up during a lunch hour'. This was a little rich from someone with no design experience whatsoever but still.

Seven years have passed though and now my requirements are slightly different. I use three different computers (desktop, work laptop and netbook) and different Web browsers (Firefox and Chromium). In addition, I consume content (Google Reader, Google Plus and identi.ca) on an Android phone so the requirement is for a reliable Chromium extension, Firefox addon and Android application, that simply supports posting and searching, for the bookmarking service.

In the intervening period, I had also played with diigo and this service is still available but leaning towards a Premium model (free basic service with paid for add ons and additional features).

All the cool cats currently tend to favour Pinboard which has a simple business model - a one-off fee that gradually increases as more users join the service. The current fee stands at $9.90 but I can hardly justify that for what is essentially a private dump of bookmarks as I would make limited use of the sharing and discovery elements.

So that was easy - delicious was acquired and subsequently sold by Yahoo! and have thankfully lost the silly del.icio.us name which now simply redirects to delicious.com.

I am using the following delicious tools:

Sorted.

speeding up Octopress generation

My site has 966 posts and 70 categories.

By default, Octopress re-generates the entire site - every single post, all the category pages, the archive pages

On my Acer Aspire One (Intel Atom 1.66GHz) netbook, the regeneration takes around 10 minutes.

There are a couple of options that can significantly reduce this time and make the write/preview/edit iterative process more tolerable.

Firstly, you can use 'rake isolate' to move all other posts into a 'stash' directory and simply process the newly created post.

    $ rake isolate['speeding']
    $ ls source/_posts/
    2012-09-20-speeding-up-octopress-generation.markdown

This reduces the generation time significantly to 18 seconds.

    $ time rake generate
    ## Generating Site with Jekyll
    unchanged sass/screen.scss
    Configuration from /home/andy/blog/octopress/_config.yml
    Building site: source -> public
    Successfully generated site: source -> public

    real    0m18.192s
    user    0m14.369s
    sys     0m1.368s

This is helpful for previewing the post as it will work on the site and fixing typos but still the time consuming site generation needs be to done prior to deployment.

    $ rake integrate
    $ rake generate

The second method is to use 'jekyll --limit-posts '. I added a new Rake task as follows:

    desc "Generate jekyll site (last 5 posts)"
    task :fastgen do
      raise "### You haven't set anything up yet. First run `rake install` to set up an Octopress theme." unless File.directory?(source_dir)
      puts "## Generating Site with Jekyll (last 5 posts)"
      system "compass compile --css-dir #{source_dir}/stylesheets"
      system "jekyll --limit_posts 5"
    end

This also significantly reduced the site generation time

    $ time rake fastgen
    ## Generating Site with Jekyll (last 5 posts)
    unchanged sass/screen.scss
    Configuration from /home/andy/blog/octopress/_config.yml
    Building site: source -> public
    Successfully generated site: source -> public

    real    0m59.061s
    user    0m40.995s
    sys     0m6.956s

Out of interest, I converted my content into Hyde (a static site generator written in Python).

Hyde generated the entire site in 9 mins 17 seconds. However, Hyde also supports incremental builds (which took just 34 seconds for a single new post).

I also tried raw Jekyll using the default Tom Preston-Werner theme. This took 2 minutes to generate the site in its entirety.

Is that Evra at left back ?

Yes. Ferguson said he would play his strongest side in Europe after last season. Why are you so surprised ?

'Oh nothing. I just can't believe it's not Buttner'.

migration complete

The last ever migration of this blog is now complete. This blog is now powered by Octopress and is a statically generated site hosted on Amazon S3.

All posts have been migrated from HTML to Markdown and every single permalink (all 954 of them) have been painstakingly checked, rationalised and consolidated.

To achieve this, I simply generated a sitemap of the Drupal site and compared this with a sitemap for a test site using Octopress after the data migration.

This unveiled a few issues that needed to be fixed:

  • Posts with the identical slug had a numeric suffix which was often incorrect or inconsistent after being mangled by various blogging platforms.
  • Some posts had the incorrect publication date (due to timezone shift) so were typically a day out.
  • Some posts were just missing after the 'exitwp' script was used to migrate from WordPress to Hyde a year ago.
  • Hyde uses a slightly different header format from Jekyll but 'sed' was able to fix this.
  • Jekyll uses a trailing slash for each post URL whereas Drupal doesn't.
  • Amazon S3 requires the canonical URL to be www.site.com with a automatic redirect to point site.com to the correct URL with the www prefix. Previously, I favoured the naked URL 'site.com'.

The permalink structure is now 'site.com/yyyy/mm/dd/hello-world/' (with a trailing slash) and will never change. Ever. Again.

I also resurrected some orphan Disqus comments by using the URL mapping tool which works brilliantly and helped identify comments associated with a non-existent URL.

I am generally delighted with Octopress as it bundles so many features I need for a blog (Disqus, Google Analytics etc) and is much easier than using raw Jekyll.

The only vague disappointment is the fact that the entire site is re-published even after a single post has been added. On my Aspire One netbook, a 'rake generate' takes 8 minutes. I might try the same process on my work laptop (faster, newer Lenovo Thinkpad) for comparison purposes.

Inevitably, there is a Jekyll fork that supports incremental deployment but the Octopress author is (understandably) reluctant to base Octopress on a fork that could quickly become stale.

Publishing the site to Amazon S3 is slightly better but, as Atom feeds get regenerated for categories, this still takes around 4 minutes.

Still, maybe this lengthy publishing process will encourage me to properly preview and get my posts perfect before publishing.

I am not sure about having all 954 posts stored in a single directory; I would rather have a sub-directory for each year but then again, being able to quickly search all posts for a keyword using 'grep' is useful.

I decided to keep the Feedburner integration for now (to avoid losing my two readers).

The use of a statically generated site also killed one of my favourite features - my legendary and award winning rotating tagline. Oh well.

Blogging like a hacker but publishing like a snail with a heavy weight strapped to his back.

the awkward second post

Octopress is great

  • Uses Google to provide site search
  • Archives builtin
  • Tag support
  • Draft posts
  • Local preview
  • Markdown markup
  • Google+, Disqus, Google Analytics support
  • Incremental deployment
  • Deployment to Amazon S3
  • Fast as lightning

Wish I'd bitten the bullet earlier.

Hello World

This is my first post in Octopress.

The text uses Markdown which is marvellous.

My favourite blogging platforms are:

  • Octopress
  • Habari
  • Drupal
  • WordPress

The BBC is a popular Web site.

End of message.

migration plan

Loose thoughts on the plan of attack for the blog migration:

  1. Install Octopress locally
  2. Configure S3 and install a dummy Web site.
  3. Use's3cmd' to upload test site to Amazon S3
  4. Test incremental uploads. This is a firm requirement.
  5. Full database backup of existing Drupal blog
  6. Take backup of Drupal installation (additional modules, scripts).
  7. Install vanilla Drupal 7 locally.
  8. Install copy of the existing Dupal blog in local version (overwrite database ?).
  9. Use the Drupal to Octopress migration script. This extracts nodes from the database and creates Markdown files for each post, This script is probably for Drupal 6 so some tweaks (major rewrite) may be needed for bleeding edge Drupal 7. URL aliasing is supposedly supported.
  10. Test the various elements in the checklist. Disqus comments need the correct domain name so will have to come last.
  11. Configure a redirect from 'nbrightside.com' to the Amazon URL. I can see trouble and lots of Googl'ing here.
  12. Place source code (Markdown posts) into GitHub repository.
  13. Put kettle on.

blog migration checklist

I am a veteran of blog migrations with the scars to prove it. Here is a handy cut out and keep checklist of the important things I normally forget:

  • Permalink structure. Try to preserve the existing permalink structure to save hours of pain. This is particularly important when using Disqus (although there is a URL migration utility for Disqus).
  • Typically, I like to have 'Archives', 'About' and a 'Contact' page.
  • Tag support including a 'Tags' page.
  • Images. I have learned to upload all photos and screenshots to PicasaWeb and intentionally de-couple images from the blog platform.
  • Sitemap support. Helps search engines index the site.
  • RSS/Atom support . Previously I have always used Feedburner (although I may follow Google's example and sever this dependency) and simply use the native feed. Less is more.
  • Comments. Static site generators are slightly limited here (compared with proper blogging platforms) so I guess I will continue to use Disqus. Mind you, for the number of comments versus spam, I may also dispense with comments and invite people to use Google+ or identi.ca.
  • Themes. It would be desirable to be able to change themes to avoid having the same look and feel and every other Octopress blog.

Please feel free to add your own tips in the comments.

Autumn migration

My Web hosting package (provided by Bluehost) expires in October. As this blog is essentially dead (the last post was a one-liner 8 months ago), the sensible and logical thing to do would be to kill the blog and save £5 a month.

Originally I purchased the domain name 'nbrightside.com' and the Web hosting for a couple of reasons:

  • I wanted to use self hosted WordPress without some of the restrictions imposed by WordPress.com
  • I wanted to play with some of the packaged applications offered by Bluehost.
  • I wanted access to a Linux environment, mainly to build, install, experiment with various open source software tools and packages which needed a LAMP stack.

It's really questionable whether I need to maintain this Web presence but, on balance, I'd like to keep the site alive for a little longer.

WordPress, Drupal, Habari et al are all fantastic blogging platforms but rather overkill for this simple, single user blog. For a while, I have been fascinated and trying to resist the temptation of the simplicity and power of static Web site generators like Jekyll and Hyde.

Last year, I even ported the complete contents of this Drupal 7 blog to a locally installed version of Hyde and laboriously fixed up lots of hyperlinks just so the Markdown looked neater.

The completely logical and sensible decision would be to simply resurrect this Hyde environment, re-sync the last couple of one liner blog posts, configure a automatic redirect and use rsync to upload this site to some alternative, cheaper (or free) Web hosting.

So, I have decided to use Octopress and Amazon S3 to host this humble, annually updated blog in the future. I may be able to reuse some of the Hyde content with judicious use of sed to convert the meta data in the header sections or I may just start afresh.

No - I am not mad.
